It wasn't too long ago when “snapshot recall” on a live console meant that you took a Polaroid photo of the desk after the soundcheck was over. Today, snapshot or scene store and recall are standard features on virtually every digital console. Resetting the entire desk at the push of a button makes digital consoles a natural choice for multi-act tours, where each engineer can quickly and accurately access settings for their band with a minimum of soundcheck time, as well as for theater productions, where each act requires reconfiguration of audio I/O. Along with snapshots, most digital desks offer extensive internal processing, such as dynamics, multiband EQ, polarity reverse and delay on every channel; onboard effects processing with complete factory and user libraries; busing and auxiliary output options; and the ability to control any audio channel via any control strip.

DiGiCo D1 Live DiGiRack

Though many digital desks have onboard audio I/O, more advanced systems employ outboard AD/DAs. Removing I/O hardware from the control surface allows manufacturers to cram an incredible amount of control over a large number of channels into a small package — 16 or 24 faders control as many as 192 channels in several layers and a single dedicated channel “strip” facilitates control over a selected or active channel. This is a boon for small venues that are hesitant to give up seats to install a large desk at front of house. Further, placing converters at stage-side shortens the analog signal path for optimum audio quality.

Just about every digital console incorporates some means of storing data, whether on a memory card via MIDI SysEx or direct connection with a computer running proprietary software — all of which means that engineers can travel with their programs and have a favorite console provided locally, reducing the tour's transportation costs.

This month, Mix surveys live sound digital consoles. If you're considering purchasing a digital desk for your next tour, make the following buyer's guide the first stop in your shopping spree.

DiGiCo's (www.digiconsoles.com) D5 Live 56 digital mixing system comprises a 64-channel work surface, a DiGiRack stage interface containing 56 A/D and eight D/A converters, and a second local DiGiRack residing next to the console, providing 56 external I/Os for inserts, effect send/returns, local monitoring and playback. The D5 Live is split into four sections of eight channels, each with an LCD touch screen. The center of the desk incorporates a “selected channel” section with dedicated hardware for channel control and an onscreen frequency display showing the EQ curve. Two master banks provide 16 faders that function as a matrix, group or aux out masters. Features include expansion slots for additional DSP and optional effects processor, snapshot recall, MADI port and a modem port for diagnostics and software updates. MSRPs: D5 Live 56 EX (40 analog, 16 digital I/O), $175,874; D5 Live 112 EX (with a second stage DiGiRack), $202,231; and D5 Live 112 FMX (monitor/FOH package), $352,436.

Featuring 40 mic/line inputs and 24 outputs, the D1 Live 40's local DiGiRack enables it to function as a direct replacement for an analog console by using existing copper multipair from the stage. The D1 Live handles 64 mono/stereo channels and can be expanded to 160 channels, with access to 224 inputs, 224 outputs and 40 buses. The D1's six independent effect processors generate reverb, delay, pitch change, multiband compressor and 28-band graphic EQ. Sixteen IPCs (insertable processing channels) include 6-band parametric EQ, compressor and delay, and may be inserted across any input or output. The D1 Live 48DP (Dual-Purpose) system extends the Live 40's facilities with a total of 48 mic/line inputs and 16 IPCs. System packages start at $68,718.

Digidesign VENUE

Based around the D-Show mixing console, Digidesign's (www.digidesign.com) VENUE system features an expandable DSP mix engine. A standard VENUE includes 48 mic inputs and can run 64 input channels with 24 graphic EQs and enough DSP power for dozens of plug-ins. All channels feature a remote-controlled head amp, delay, 4-band parametric EQ with analog emulation mode and dual dynamics processors. VENUE includes D-Verb, delay, pitch and dynamic plug-ins, and supports plug-ins from other manufacturers. The Assignable Channel Section (ACS) enables adjustment of all parameters for any selected channel. Optional sidecars may be added to increase fader count.

VENUE's 19-inch Stage Rack provides analog audio I/O for stage signals, accommodating up to 48 remote-controlled mic/line preamps and A/D converters. The FOH Rack contains the D-Show mix engine and furnishes audio connectivity at the mix position.

VENUE can be interfaced directly to Pro Tools using Digidesign's FWx card or TDM Record Option. A standard VENUE system is $62,995.

Harrison Trion

Jointly developed by Harrison (www.harrisonconsoles.com) and Showco, the LPC's extensive automated input selection system greatly reduces the number of active channels required for a given section of a performance, while proprietary IKIS event-based automation provides instant recall and reset of every function on the console (up to 10,000 setups). The LPC provides three mic and one line input per channel, motorized faders and pots, and 5.1 panning. Up to 32 mix buses or aux sends are available, as are 32 matrix outs. Audio I/O is 24-bit, while internal signal processing uses Harrison's 40-bit Wide Pipe path. A TFT interface, alphanumeric display on all faders and 16 remote VCA faders help users manage shows with large numbers of inputs.

Designed with a small footprint and employing the company's Wide Pipe signal path, Trion runs on Harrison's IKIS platform and features built-in 15-inch monitors for a dedicated view of channel settings. Harrison's PreView waveform envelope display gives the operator a 20-second-long waveform view of any audio source. Trion can incorporate from 32 to an unlimited number of dual input channels, each with 16 or 32 aux sends and 24, 48 or 96 bus assignments (dependent upon configuration). Channel controls and assignments are instantly accessible as vertically oriented strips or “folded out” across eight faders for true knob-per-function adjustment. The DTC (Digital Tools Card) adds a 20-second loop recorder and 32 digital bus limiters with look-ahead intelligence — becoming a gateway to DSP plug-ins. Adding a portable 8-fader panel and screen, a remote operator can control FOH or monitor mixes from anywhere in the venue.

InnovaSon Sy48

InnovaSon's (www.innovason.com) Sy80 provides 80 inputs, 80 outputs and 48 mix buses operating at 48 kHz/24-bit, with 32- to 40-bit internal processing. Fader-per-channel architecture provides simultaneous access to all 80 channels. In addition to the motorized fader, each channel has a dedicated LED meter and Cue/Select/Mute buttons. A Channel Control section provides instant, dedicated control over channel settings, while a 15-inch retractable screen displays channel information. InnovaSon's XFAD expansion fader combinations allow an engineer to group several sources for control under one input fader. The Sy80 is controlled by Sensoft 8 PC-compatible software for editing and archiving of up to 1,000 pages per show. Export and import functions allow file transfers from console to PC and vice versa.

Housed in a compact package, InnovaSon's Sy48 provides 64 channels with 48 local mic/line inputs, 16 local line inputs and 16 local line outputs for aux, inserts and bus sends. The Sy48 maintains InnovaSon's fader-per-channel architecture, with Level Meter, Mute, Cue and Select buttons per channel. Faders are user-configurable as inputs, VCAs, groups, buses, aux, XFAD, matrix or crossfaders. Console features include a central control panel for channel parameters, 12-inch fold-down screens and stereo monitoring with PFL, AFL and APL (After Processing Level) listening on headphones or via allocated outputs. The Sy48 includes InnovaSon's Sensoft management software, facilitating instant recall of console configurations; snapshot automation with manual or MIDI synchronization-enhanced Q/Page display and control for theater applications; and offline programming for show preparation.
